Specification of Letters Patent.

To all whom it may concern:

Be it known that we, FREDRICK 0. C01.- LAB, of Ashtabula, in the county of Ashtabula and State of Ohio, and HERBERT E. WETHERBEE, of Cleveland, in the county of Ouyahoga and State of Ohio, both citizens of the United States, have invented certain new and useful Improvements in Apparatus for Sampling Ores; and we do hereby declare the following to be a full, clear, and exact description of the invention,'such as will enable others skilled in the art to which it appertains to make and use the same. Our invention relates to an improvement in apparatus for sampling ores.

The usual custom is to sell Lake Superior iron ore on a guarantee to be of a certain quality, and if the analysis shows it to be better than the guarantee a premium is paid, and if of a lower grade a penalty is enforced. The sampling is done by disinterested parties acting as umpires between the buyer and seller, and each cargo of ore is considered as a unit and every effort is made to get a fair averagesample of each cargo ple of the cargo have greatly increased,

This has been ofiset by increasingthenumber of men engaged in sampling, but 1t is generally admitted that under the present conditions of unloading a mechanical sample would be desirable.

The object of our invention is to provide means for automatically securing a sample from each bucket of ore taken from the boat,

and it consists in a container carried by one fine ore are taken the size of the boats enof the ore into the container each time the In the accompanying drawings, Figure 1 is a diagrammatic view in side elevation of the bucket of an unloading machine, also showing in dotted lines, the position of the jaws of the bucket when the latter is open. Flgs. 2 and 3 are views in elevation of thecontainer and its supporting die and block. Figs. 4: and 5 are views in elevation of the plunger. Figs. 6 and 7 are enlarged views I of the die through which the ore is forced into the container showing in dotted lines the shape of the bore in the die. Fig. 8 is an end view of the block which supports the rear end of the container, and Figs. 9 and 10 are views of the container.

1 and 2 represent the two j bers of an unloading bucket which when closed and filled are in the position shown in full lines in Fig. 1, and which when open approximate the position shown in dotted lines.

Secured to the jaw 1, at is the die block '3, and secured to the jaw 2 is the plunger 4:, the latter being so located as to enter the bore in the die each time the bucket are moved into closed the jaws of position. The die 3 consists of a metal block, preferably manganese steel, having side flanges 5 for thepassage of the screws, rivets or other devices-which secure it to the edge thereof,

J aws or memthe inner face of the side of the bucket sec- -tion or jaw, and provided with a central bore the two ends of which are tapered as shown in, dotted lines at 6 and 7 Fig. 7 while'the intermediate section 8 of the bore is cylindrical and-of less diameter than the outer end of the taperingsection 6, so that the ore, as it is forced into the die, will become wedged and packed in the smaller cylindrical section of the die and not fall out during the opening and closing move ments of the aws.

;] The rear tapermg end 7 of the bore is ,to receive and support the front end of the the other jaw for forcing a small quantity container 9, the rear end of the latter being adapted to take over the rear end of the container when the latter is properly seated on the block 10, the clamp being locked in place by the pin 13. From the foregoing it will be seen that When the rear end of the container 9 is released from the block 10 it can be readily and quickly connected to and disconnected from the die, the tapering end 7 of the bore permitting of the freedom of movement'necessary to the attachment and release of the container and also operating to properly center the container with relation to the die. It will also be seen that the container can be quickly removed and replaced by another so that there will be but little if any interference with the normal working of the unloading apparatus.

The plunger 4 is secured to the jaw 2 in alinement with the bore of the die so that as the jaws approach each other in closing,

the plunger will enter the die and force the ore, which will have filled the bore of the die during the movement of the jaws toward each other, into the intermediate restricted position 8 of the bore and into the container at the rear of the die.

The container 9 is preferably slotted as shown in Fig. 9 to facilitate the removal of the ore from the container. The ore packs in the latter and by slotting the container it is rendered more flexible so that when tapped with a hammer or other tool the ore will be more readily dislodged. If desired the container may be made of two sections hinged together as shown in Fig. 10, which construction is better adapted for handling wet or sticky ore.

The hinged clamp 12, for locking the rear end of the container to the block 10, is provided at its pivoted end with a shoulder or stop 14:, which, when the clamp is turned outwardly to release the container, abuts against the block and holds the clamp 12 approximately horizontal and in a position to prevent the container from accidentally sliding of the block during the operation of removing the latter from the bucket With the bucket provided with the attachmentdescribed, it will be seen that each time the bucket is filled, an equal amount of we will be caught and forced into the die and from the latter into the container, and each container is of suflicient length so that the bucket can be filled a number of times before the container becomes filled. The filled or partly filled container may be removed and an empty one inserted when the machine is stopped for oiling so as not to of ore is takeneach time the bucket is filled during the various stages of unloading from the start to the finish, thus dispensing altogether with the necessity of going into the hold and eliminating entirely the possibility of injury by the unloading machine or by falling ore.

WVhile we have described our invention in certain preferred embodiments, modifications might be made without departing from the invention. Therefore we do not wish to be understood as limiting the invention to the particular arrangements, constructions and devices shown and described except so far as certain of the claims herein are limited thereto by their express language.

Having fully described our invention what we claim as new and desire to secure by Letters-Patent, is:

1. In an apparatus'for sampling ore, the combination of a bucket composed of a plurality of jaws, a container carried by one aw and a plunger carried by another jaw and adapted to force ore into the container each time the jaws of the bucket are closed.

2. In an apparatus for sampling ore, the combination of a bucket composed of two jaws, a container detachably, carried by one jaw and plunger carried by the other jaw and adapted to force ore into the container each time the bucket is filled.

3. In an apparatus forsampling ore, the combination of a bucket having two jaws, a die secured to one jaw, a plunger secured to the other jaw and adapted to enter the die each time the bucket is filled, and a container connected with the die so as to receive the ore forcedinto the latter by the plunger.

4. In an apparatus for sampling ore, the combination of a bucket having two jaws, a die secured to one jaw, a plunger secured to the other jaw and a container removably secured to the die and forming a continuation thereof.

5. In an apparatus for sampling ore, the combination of a bucket having two jaws, a die secured to one jaw, a plunger secured to the other jaw and adapted to enter the die each time the bucket is filled, and a tubular container supported at one end by the die and detachably secured at its other end to a support.

6. Inan apparatus for sampling ore, the combination of a'bucket having two jaws, a die secured to one jaw, the said die having a tapering bore whereby the ore will be compacted during its passage through the die, a container to receive the ore forced through the die and a plunger carried by the other jaw of the bucket and adapted to enter the die each time the bucket is filled.

7 In an apparatus for sampling ores, the combination of a bucket having two jaws, a die secured to one jaw, a block secured to said jaw in rear of the die, a movable container mounted at its front end in the die and detachably secured at its rear end to the block, and a plunger secured to the other jaw of the bucket and adapted to enter the die each time the bucket is filled.

8. An attachment for ore unloading machines consisting of a plunger, a die coacting with the plunger and a removable container communicating with the bore of the die and adapted to receive the ore forced through the die by the plunger.

9. An attachment for ore unloading machines, consisting of a plunger, a die having a bore flaring outwardly at its front end, a removable container communicating with the bore of the die at the rear end of the latter for receiving the ore forced through the die by the plunger.

In testimony whereof, we have signed this specification in the presence of two subscribing witnesses.
